Is that $.00001=\frac{1}{10} (3x+2)$?

2. anonymous

i think it might be an exponent

3. anonymous

1/10 ^ 3x+2

$.00001=\frac{1}{10}^{3x+2}$$.00001=\frac{1^{3x+2}}{10^{3x+2}}$$.00001=\frac{1}{10^{3x+2}}$$0=\frac{100000}{10^{3x+2}}$$10^{3x+2}=100000$$10^{3x+2}=10^5$ So $3x+2=5$$3x=3$$x=1$

.00001 = (1 / 10)^(3x +2) Multiply and divide by 100000 on left hand side 1/100000 = 1/10^(3x+2) 100000 = 10^(3x + 2) 10^5 = 10^(3x +2) here base values are equal, so equate the exponents 5 = 3x +2 -2 -2 ------------------ 3 = 3x divide by 3 on both sides 3/3 = 3x/3 1 = x
